Description

Human CD99 (Cluster of Differentiation 99) ELISA KitThe Human CD99 (Cluster of Differentiation 99) ELISA immunoassay kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Human CD99. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human CD99 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each

The Human CD99 (Cluster of Differentiation 99) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human CD99. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human CD99 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human CD99, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human CD99. You can calculate the concentration of Human CD99 in the samples by comparing the OD of the samples to the standard curve.

Works Great
Size: 8 Fl Oz (Pack of 1)
I"ve used Stabil gas treaments for year but never this particular type. With gas the way it is, I decided to see how it might help my mower and also my older truck. My older push mower which admittedly doesn't get pampered and petted seems to love it. Either it's grateful to get anything special or this stuff really has helped. The first tank seemed a little smoother but by the second I could hear the difference and feel it with the smoother sound and seems more power. It's easy to mix and use and Stabil is a well known reputable company.

Easy and worked seamlessly with the new Apple MacBook Pro
Style Name: MacBook Pro 14" (M4), Configuration: 3 years
This was our first (Apple MacBook Pro M4) and big purchase directly on Amazon. I was not concerned about the order and product, but more concerned about the AppleCare+ not being connected directly to the device (after reading some reviews). However, I am happy to report that this was the first thing I checked as soon as we set up our computer. We are set for 3 years ... so thank you, Amazon and Apple, for working out the backend stuff and making our lives easier. It worked for us. It was easy, and I am happy with the overall quality of the process. Oh, don't forget it was cheaper than buying yearly from Apple directly.

Don't buy AppleCare from Amazon, won't "attach" to your device automatically
Style Name: MacBook Pro 14" (M4), Configuration: 3 years
As another reviewer said, Amazon should not be allowed to sell digital items like these and fail to deliver them. That's called a scam. I have yet to receive my AppleCare agreement, but Amazon was more than glad to charge my Amex right away. Purchasing AppleCare from Amazon will only get you to a download of a PDF of the general terms and conditions, from your "Software Library", but it is not YOUR actual user agreement, and will not register on your device. Amazon will not help either, they will refer you to Apple support, and Apple will tell you that without an Agreement Number, they can't apply your AppleCare to your device. Since the PDF Amazon directs you to is a simple General Terms and Conditions document, there is no Agreement Number. In addition, the purchase invoice doesn't show this Agreement Number nor the device's Serial Number (which Amazon claims is recorded with the purchase... it's not) Save yourself the headache, and buy AppleCare direct from Apple, it will be about $60 more, but the "savings" is not worth dealing with this Amazon stuff. Amazon will also refuse to process a refund, stating that "only Apple can do that". Guess Amazon is telling you to contact your credit card and initiate a chargeback for services not received as paid.

Was skeptical but it worked out of the box
Style Name: MacBook Air 13" (M4), Configuration: 3 years, Style Name: MacBook Air 13" (M4), Configuration: 3 years
Was skeptical at first but decided to pull the plug and get the m4 laptop with 3 years of apple care and it works. Haven't even opened an email or anything, laptop was still fresh out of the box. When I remembered I bought apple care and decided to check. Applied instantly as far as I know once I linked my apple account on the first boot up with internet! Good stuff

DO NOT PURCHASE WITH YOUR MACBOOK OR OTHER APPLE DEVICES
Style Name: MacBook Air 13" (M4), Configuration: 3 years, Style Name: MacBook Air 13" (M4), Configuration: 3 years
I bought this along with my MacBook. And here is why you SHOULDN'T: 1. They NEVER sent me an AppleCare+ Agreement. You will only be able to download a General Terms & Conditions file. 2. I bought: AppleCare+ for 13-inch MacBook Air (M4) (3 years) and in the General Terms & Conditions that I downloaded, looking for my AppleCare+ Agreement #, it NEVER mentioned Macbook Air as a covered device. It was meant for other smaller devices, which is why it's cheaper. 3. Like I mentioned, since I never received an agreement, I never got an agreement #. 4. Since this AppleCare wasn't actually meant for a MacBook, it didn't connect automatically to my computer. So when I went to talk to Apple and Amazon, without an Agreement # you can do ANYTHING. If you purchase it, read through your General Terms and Conditions and find an excuse to ask for a FULL REFUND. Since this didn't cover my computer, I was thankfully able to get one, but it was a pain trying to talk to customer support and apple.
